PHP sleep() no funciona

Question

Estoy haciendo un archivo php que ejecutará un evento después de que hayan transcurrido cinco minutos. De los documentos, parece que esperar cinco minutos solo requeriría , pero esto no está funcionando. He probado todo el otro código, y funciona bien hasta que agregue la línea sleep.

<?php 
/** 
* Twitter App 
* bagelBack.php 
* Takes parameters from $_POST and creates a tweet 
* RKoutnik, 2012 
* Code originally found on http://140dev.com/twitter-api-programming-tutorials/hello-twitter-oauth-php/ 
*/ 

$name = '@'.$_POST['twitterName']; 
$type = $_POST['bagelType']; 

/* BEGIN CONTENT SPINNER TO IMPRESS LYNK */ 
$bagels = array(
    0 => "bagel", 
    1 => "breakfast treat", 
    2 => "doughy food-type item", 
    3 => "round yeast-raised munchie", 
    4 => "doughnut-shaped roll", 
    5 => "hard-crusted treat" 
); 
$finished = array(
    0 => "finished toasting", 
    1 => "completed toasting", 
    2 => "stopped being raw", 
    3 => "concluded the toasting phase", 
    4 => "been sucessfully executed", 
    5 => "been roasted to a crisp" 
); 

$food = $bagels[array_rand($bagels)]; 
$fin = $finished[array_rand($finished)]; 
sleep(300); 
$tweet_text = $name.", Your ".$type." ".$food." has ".$fin; 

$result = post_tweet($tweet_text); 
echo "Response code: " . $result . "\n"; 

function post_tweet($tweet_text) { 

    // Use Matt Harris' OAuth library to make the connection 
    // This lives at: https://github.com/themattharris/tmhOAuth 
    require_once('tmhOAuth.php'); 

    // Set the authorization values 
    // In keeping with the OAuth tradition of maximum confusion, 
    // the names of some of these values are different from the Twitter Dev interface 
    // user_token is called Access Token on the Dev site 
    // user_secret is called Access Token Secret on the Dev site 
    // The values here have asterisks to hide the true contents 
    // You need to use the actual values from Twitter 
    $connection = new tmhOAuth(array(
    'consumer_key' => '[redacted]', 
    'consumer_secret' => '[redacted]', 
    'user_token' => '[redacted]', 
    'user_secret' => '[redacted]', 
    'curl_ssl_verifypeer' => false 
)); 

    // Make the API call 
    $connection->request('POST', 
    $connection->url('1/statuses/update'), 
    array('status' => $tweet_text) 
); 

    return $connection->response['code']; 
} 
?>

Pruebe agregar set_time_limit(0); en la parte superior del documento. Lo más probable es que esté llegando al "tiempo máximo de ejecución" y que el script finalice.
